yes ten is natural,whole, integers,rational

Step-by-step explanation:

because natural contains all numbers wiThout 0 and whole contains all numbers with 0 so 10 is both of them.Integers are the number which is not a fraction,it is a whole number.And 10 is a rational number because all integers are rational.But it is not irrational.

The table contains data on the admission price (in dollars) for one-day tickets to 10 theme parks in the United States. Find t

Bezzdna [24]

Step 1: put the numbers in order form least to greatest
25,40,42,42,43,43,52,60,60,65
step 2: find the median
step 3: place parentheses around the numbers from above and below the median
(25,40,42,42,)43,43,(52,60,60,65)
step 4: find the median from the below parentheses and from the parentheses above
bellow = 41 bc 40 and 42 cant be the median so between those two is 41
above = 60
step 5: subtract below and above medians
60 - 41 = 19
so 19 is your answer

Find both the vector equation and the parametric equations of the line through (0,0,0) that is perpendicular to both uequals

Pavel [41]

Complete Question:

Find both the vector equation and the parametric equations of the line through (0,0,0) that is perpendicular to both $u = < 2, 0, 2>$ and $w = < -2, 1, 0>$ where t = 0 corresponds to the first given point.

Answer:

Vector equation: (x, y, z) = (0, 0, 0) + t ( u x w)

Parametric equation:

x = -2t

y = -4t

z = 2t

Step-by-step explanation:

Since the line is perpendicular to $u = < 2, 0, 2>$ and $w = < -2, 1, 0>$ , we will find the cross product of u and w

$u \times w = \left[\begin{array}{ccc}i&j&k\\2&0&2\\-2&1&0\end{array}\right] \\\\u \times w = i(0-2) -j(0+4) + k(2)\\\\u \times w = -2i - 4j + 2k\\\\u \times w = < -2, -4, 2>$

The equation of the line can be given by:

(x, y, z) = (0, 0, 0) + t ( u x w)

(x, y, z) = (0, 0, 0) + t < -2, -4, 2 >

x = -2t, y = -4t, z = 2t

Please help!

IrinaVladis [17]

Still don't know what the given line is, so I'm just going to attach images of the graphs of each equation.

Graph 1: y = -2x

Graph 2: x = 4

Graph 3: y = x

Graph 4: y = 3

Hope this helps!
